Locating the Mainboard Fuse on Epson WorkForce WF-7610 and WF-7620

Question:
I'm working on uncasing an Epson WorkForce WF-7610 / WF-7620 to remove the case and scanner. Where exactly is the mainboard fuse located on these printers?

Answer:

On Epson WorkForce models such as the WF-7610 and WF-7620, the mainboard fuse is a common point of failure when the printer encounters power-related issues or errors such as 0x9A or 031006. The mainboard typically includes a small surface-mounted fuse, usually marked as F1 (and in some cases, also F2 or F3 on different models). These fuses are safety components designed to protect the board's circuits.

To help you identify the exact location, we've compiled reference images and details for the F1 fuse position on most common Epson mainboards. You can find these resources on our product page: F1 Fuse (also F2, F3) for Epson Mainboard - Fix Error 0x9A or 031006 (https://bchtechnologies.com/products/f1-fuse-also-f2-f3-for-epson-mainboard-fix-error-0x9a-or-031006-on-wf-7720-wf-7710-wf-3640-et-8550-xp-15000?_pos=2&_sid=0419251d7&_ss=r).

When checking the fuse:

• Look for tiny rectangular components labeled with "F1" (or occasionally "F2"/"F3") silkscreened on the board.

• If the fuse is blown, it may need to be replaced with an identical rating. Some technicians bridge the fuse temporarily for testing, but the safer long-term solution is a proper replacement.

• Always ensure the printer is unplugged before inspecting or working on the mainboard.

These fuses play a vital role in preventing further board damage, so if your WF-7610/7620 is showing mainboard-related error codes, checking F1 is an important diagnostic step.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. So, we're not able to provide remote troubleshooting, suggestions, or support for printer repairs. We do offer in-person diagnostics and repair services through our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Because of high demand, this operates on a first-come, first-served basis, and wait times can sometimes be a few weeks. Our services include both full printer repairs and part-level fixes, though we acknowledge our pricing may not always be the lowest option. For that reason, we recommend starting with self-help research. A great place to begin is our YouTube channel homepage (https://youtube.com/@bchtechnologies). By using the search icon next to the "About" section, you can quickly find specific videos from our nine years of content, and YouTube may also suggest other helpful videos from additional creators.
